SPRING BED-BOTTOVI SPECIFICATION forming part of Letters Patent No.289,493, dated December 4, 1883.

` Application iiled August 17, 1883. (No model.)

of the United States, residing at SouthBend, in the county i of`St.-Joseph and State of Indiana, have invented certainnew anduseful;

Improvements in Bed-Slats, of `which the following is a speciiication,Areference being had therein to the accompanying drawings.

My invention relates to certainnew and` useful improvements in elasticbed-bottoms, and it consists `in'arranging the slats of abedstead atequal distance apartto form a bedbottom, and support them in saidposition on elastic material. i

The object of my invention is, first, to

form a cheap and durable elastic bed-bottom,

adapted for use on all ordinary bedsteads; second, to construct theessential features of my invention in such a manner that they mayv beapplied to the common slat-bottom bedstead, to change the same into aspring-bottom bedstead at a trifling expense. I attain these objects bymeans of the peculiar construction and ,p arrangement of the variousparts of my invention, which will be more i'ully pointed out anddescribed in the specification and claims, referring to the drawingsaccompanying this application and forming a part ofthe same, in which-Figure l is a bottom plan View of my invention, showing the differentparts in place. Fig. 2 is a vertical sectional view ofthe same, and Fig.8 is a cross-section of the longitudinal slats andrings.

Similar letters refer to similar parts throughout the drawings. A

Reference being had to the drawings, A represents an ordinary bedstead,havingfootboards, side rails, and head-boards.

rails, B, in the usual u form, to ,receive the ends of cross-slats a, asshown `in Fig.'2, `said cross-slats being arranged to extend from theinner face of one side rail to the inner face of the opposite rail, andare usually placed one at the foot and one at the `head of the bedstead,as shownin Fig. 2; but in case the ordinary cross-slats are used(instead of extra slats prepared for the purpose) to form the bed.

p A pro-- 4o jection, d, is formed on the inner face of side.

Y longitudinal strips d', then an extra cross-slat is placed across thecenter of the bed in the usualform, as shown in Fig. l. Said crossslatsc are formed about two inches wide, and Of sufiicient length to reachacross the bedstead and on the under side ofthe same. Elastic web l)(preferably rubber) is secured by screw-bolts or rivets, each end ofsaid web b being secured to each end of slats c, the remaining portionlbeing loose, `but lying close to the slat a.

Rings c are formed of metal, rounding on their outer surface and angularon their innersurfaces to fit around the cross-slat c and web Z2, asishown in cross-section -in Fig. 2. Said rings, when placed in positionon slats c, serveto keep the slats d in place and hold the elastic webagainst the same, while the web b is allowed to yield when weight isplaced on said slats.

In forming a bed-bottom with my invention, cross-slats a are prepared inthe usual form, when elastic web is secured by its ends to the ends ofthe slats a by means of nails or screwbolts e, said web Z) being aboutthe same width as `the slats a, and of the same length, said web beingdrawn smoothly along the under face of slats a. Slats a are then placedin position in a recess formed in projection d, one at the foot and oneat the head of the bed, and when desired, one at the center of the Alongitudinal slat, b, is then inserted between the elastic web Z and theslats ce, said slat resting by its ends on the web b. A ring, i

like manner, followed by the rings c, and thus the operation is repeateduntil the bed-bottom is completed. rlhis construction forms a cheap` anddurable elastic bed-bottom, that can be easily applied to almost anybedstead in use.

I am aware of the Patent No. 52,658, February 20, 1866, itsconstruction, and the arrangement of the various parts of ythe same, andI therefore do notbroadly claim the same; but

What I do claim is as follows:

In a bed-bottom, the cross-slats c, construeted'as described7 wherebythey will fit in In testimony whereof I affix my signature and rest onthe interior supportng-langeA of in presence of two Witnesses.

a Slat bedstead, having each a rubber web or strip, b, secured to itslower sideI and at the extremities7 as shown7 in combination withlongitudinal slats d', and the rings c, all oonstrueted and arrangedsubstantially as shown and specified.
